My local pet food store just got these in, and I was curious about them. I guess they're suitable for dogs and cats (I have two cats, so I'm posting this in the cat forum). I bought a can of beaver just to see how my cats would like it, but haven't fed it to them yet.

Now the feeding instructions state:

A 1/8 can a day for every 18 pounds of body weight.

Now I wasn't sure if this is as a supplement only, or if that's sufficient as their primary food source, as this would mean a single can would last over a week for a smaller cat?
